Impact of trichothecenes on <i>Fusarium</i> head blight [ <i>Fusarium graminearum</i> ] development in spring wheat ( <i>Triticum aestivum</i> )
Bibliographic record
Abstract
>Fusarium head blight pathogens (Fusarium spp.) produce trichothecenes that have been demonstrated to play a role in the pathogenesis. To test the impact of trichothecenes on a broad range of genotypes, 18 spring wheat lines (Triticum aestivum) were inoculated with two Fusarium graminearum strains, the genetically modified GzT40 strain, which could not produce trichothecene, and the wild parental Gz3639 strain. During 3 weeks of observation, the two fungal strains showed extreme differences in aggressiveness in all but three of wheat genotypes tested. While the GzT40 mutant did not spread into the rachis, the wild-type strain quickly spread in the spike. This work confirms earlier findings that trichothecenes are a principal determinant of F. graminearum aggressiveness on most spring wheat cultivars. Therefore, trichothecenes may serve as a useful screening tool in programs breeding for resistance to Fusarium head blight of wheat.Key words: trichothecenes, deoxynivalenol, mycotoxins, Fusarium head blight, Fusarium graminearum, spring wheat, Triticum aestivum.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
